the first hack will enable you to use a lower backlight
this is sufficient except when you're out in bright sunlight.
(if you're outside but it isn't a sunny day, the dim backlight will still be enough!!
)
(why couldn't the manufacturer allow the user to set any backlight level???
)
the second hack will enable you to use the phone even if the battery discharges below 35%
will soon post a little app to set the backlight without the need to soft reset, very cool.
(needs to have the user interface cleaned up. it is all hungarian at the moment hahaha. nah, it wasn't me who wrote it. i discovered only the registry hack.
)
second hack is easy but i already discovered a little side effect and there may be more, still untested at the moment. the known side effect is that if you do a soft reset, you will need to turn on the phone module manually
(it takes just one click...
)
will probably have an app to set this too, but until that just go to the registry:
HKEY_LOCAL_MACHINE/init
and there delete Launch71
(batterynotify
) key.
soft reset and woo hoo!
that's all!
btw a few results...
with the new dim backlight and cpu running at 200 mhz
(cpu underclock can be set in control panel
) a meagre 1300 mAh battery
(not the original battery!
) discharged by only 30%, i.e. 70% of the charge was still available after 1 hr 16 mins of continuous use of gprs.
with full backlight the phone and gprs was already disabled after the same 1 hr 16 mins.
if you do both hacks, this 1300 mAh battery may last 4 hours of gprs depending on cpu settings. the original 1860 mAh battery will fare even better
(5-6 hours of continuous gprs?
).
double this result again and that will be the battery life with dim backlight without using the phone and gprs.
especially if you still have the original battery with full capacity (i do have the original but the capacity is not the best.. so these hacks are very handy for me)..
